The May NATO summit in Chicago is bringing delegations from some 40 countries--leaders from NATO countries and nations who are contributing troops to the Afghanistan conflict--a major topic of discussion at the summit. Presidents or Prime Ministers, Defense Secretaries and Secretaries of State or Foreign Ministers will be feted at a series of dinners on May 20.

Last month, the White House announced President Obama will host what is being billed as a "working dinner" with the NATO heads of state on May 20 at Soldier Field, not far from the McCormick Place complex which is the headquarters for the the summit.

First Lady Michelle Obama will also be throwing a spouse dinner that night--with one possible location the Symphony Center complex associated with the Chicago Symphony.
